Plaqueta de corteCutting plate
La presente invencion se refiere a una plaqueta de corte y a una herramienta de perforacion.The present invention relates to a cutting plate and a drilling tool.
Una plaqueta de corte conocida por el depositante se divulga en el documento de los Estados Unidos US6860344. Esta plaqueta de corte incluye un alma que se extiende axialmente y tres ramas identicas que se extienden radialmente desde el alma. Las ramas estan desviadas angularmente en 120°. El documento de los Estados Unidos US 2002/195279 divulga igualmente una plaqueta de corte.A cutting plate known to the depositor is disclosed in US document US6860344. This cutting plate includes an axially extending soul and three identical branches that extend radially from the soul. The branches are angularly offset by 120 °. US 2002/195279 also discloses a cutting plate.
Cada rama presenta una porcion proximal conectada al alma, una porcion distal y una porcion central que une la porcion proximal y la porcion distal.Each branch has a proximal portion connected to the soul, a distal portion and a central portion that joins the proximal portion and the distal portion.
Cada rama presenta una arista de corte que se extiende sobre la porcion proximal, la porcion distal y la porcion central.Each branch has a cutting edge that extends over the proximal portion, the distal portion and the central portion.
Un inconveniente de una plaqueta de corte de este tipo reside en su escasa capacidad para evacuar las virutas de materia durante la perforacion. Tambien, durante una perforacion, las virutas de materias tienden a acumularse arrastrando un aumento de los rozamientos ejercidos sobre la plaqueta de corte. Desde ese momento, la velocidad de perforacion disminuye y el desgaste de la plaqueta es mas importanteA drawback of such a cutting plate lies in its poor ability to evacuate the chips of matter during drilling. Also, during a drilling, the shavings of materials tend to accumulate dragging an increase of the frictions exerted on the cutting plate. From that moment, the drilling speed decreases and platelet wear is more important
La invencion tiene por objeto remediar este inconveniente.The invention is intended to remedy this inconvenience.
La invencion se refiere a una plaqueta de corte disenada para estar fijada a un extremo de un cuerpo de herramienta con el fin de arrastrarse en rotacion alrededor de un eje, que incluye:The invention relates to a cutting plate designed to be fixed to one end of a tool body in order to creep around a shaft, which includes:
- un alma que se extiende axialmente; y- a soul that extends axially; Y
- al menos una primera rama y una segunda rama que se extienden radialmente desde el alma, comprendiendo la primera rama y la segunda rama cada una:- at least a first branch and a second branch that extend radially from the soul, comprising the first branch and the second branch each:
• una porcion proximal conectada al alma, una porcion distal y una porcion central que conecta la porcion proximal y la porcion distal; y• a proximal portion connected to the soul, a distal portion and a central portion that connects the proximal portion and the distal portion; Y

- la porcion distal de la primera rama esta dispuesta radialmente hacia adelante con respecto a la porcion central de la primera rama; y- the distal portion of the first branch is arranged radially forward with respect to the central portion of the first branch; Y
- la porcion central de la segunda rama esta dispuesta radialmente hacia adelante con respecto a la porcion distal de la segunda rama.- the central portion of the second branch is arranged radially forward with respect to the distal portion of the second branch.
Durante una perforacion, el movimiento descrito por la plaqueta de corte es helicoidal. De esta manera, el movimiento es una combinacion simultanea de una traslacion y de una rotacion.During a perforation, the movement described by the cutting plate is helical. In this way, the movement is a simultaneous combination of a translation and a rotation.
La expresion “radialmente hacia adelante” hace referencia al sentido de rotacion de la plaqueta de corte.The expression "radially forward" refers to the direction of rotation of the cutting plate.
La expresion “axialmente hacia adelante” hace referencia al sentido de traslacion de la plaqueta de corte.The expression "axially forward" refers to the direction of translation of the cutting plate.
La porcion distal de la primera rama esta dispuesta radialmente hacia adelante con respecto a la porcion central de la primera rama.The distal portion of the first branch is arranged radially forward with respect to the central portion of the first branch.
En otras palabras, con vista desde arriba, la porcion distal de la primera rama esta dispuesta hacia adelante con respecto a la porcion central de la primera rama, refiriendose adelante al sentido de rotacion.In other words, with a view from above, the distal portion of the first branch is arranged forward with respect to the central portion of the first branch, referring forward to the direction of rotation.
De esta manera, la arista de corte de la primera rama permite guiar hacia el interior las virutas de materia con vistas a evacuarse por el cuerpo de herramienta.In this way, the cutting edge of the first branch allows material chips to be guided inwards with a view to being evacuated by the tool body.
La porcion central de la segunda rama esta dispuesta radialmente hacia adelante con respecto a la porcion distal de la segunda rama.The central portion of the second branch is arranged radially forward with respect to the distal portion of the second branch.

De esta manera, la arista de corte de la segunda rama permite guiar hacia el exterior el excedente de virutas de materia que no han podido evacuarse por el cuerpo de herramienta con el fin de limitar el riesgo de atasco a la altura del alma.In this way, the cutting edge of the second branch allows the excess of material chips that have not been able to be evacuated through the tool body to be directed outward in order to limit the risk of jamming at the height of the soul.
Entonces, la plaqueta de corte segun la invencion permite facilitar la evacuacion de las virutas de materia.Then, the cutting plate according to the invention allows to facilitate the evacuation of the shavings of matter.
La plaqueta de corte segun la invencion puede incluir una o varias de las siguientes caracterfsticas.The cutting plate according to the invention may include one or more of the following characteristics.
Siguiendo una caracterfstica, la arista de corte de la primera rama presenta, al menos sobre la porcion distal y la porcion central, un perfil concavo; y la arista de corte de la segunda rama presenta, al menos sobre la porcion distal y la porcion central, un perfil convexo.Following a characteristic, the cutting edge of the first branch presents, at least on the distal portion and the central portion, a concave profile; and the cutting edge of the second branch has, at least on the distal portion and the central portion, a convex profile.
En una forma de ejecucion preferente, la plaqueta de corte incluye al menos una tercera rama que comprende:In a preferred embodiment, the cutting plate includes at least a third branch comprising:
• una porcion proximal conectada al alma, una porcion distal y una porcion central que conecta la porcion proximal y la porcion distal; y• a proximal portion connected to the soul, a distal portion and a central portion that connects the proximal portion and the distal portion; Y

los puntos de ataque de la primera rama, de la segunda rama y de la tercera rama estan dispuestos en un mismo plano radial.the attack points of the first branch, the second branch and the third branch are arranged in the same radial plane.
Durante el inicio de la perforacion, los puntos de ataque de la primera rama, de la segunda rama y de la tercera rama descansan contra la materia. Entonces, el eje de la plaqueta de corte se extiende perfectamente de manera perpendicular a la materia. De esta manera, se facilita el posicionamiento de la plaqueta de corte.During the beginning of the drilling, the attack points of the first branch, the second branch and the third branch rest against the matter. Then, the axis of the cutting plate extends perfectly perpendicular to the material. In this way, the positioning of the cutting plate is facilitated.
Preferentemente, los puntos de ataque de la primera rama, de la segunda rama y de la tercera rama estan dispuestos alrededor de un vaciamiento habilitado en un extremo del alma.Preferably, the attack points of the first branch, the second branch and the third branch are arranged around an enabled emptying at one end of the soul.
Un vaciamiento de este tipo permite evitar que el extremo del alma, que presenta una velocidad de rotacion nula, llegue a frenar la plaqueta de corte por rozamiento.An emptying of this type makes it possible to prevent the end of the soul, which has a zero rotation speed, from stopping the friction cutting plate.
Preferentemente, el vaciamiento esta centrado sobre el eje de la plaqueta de corte.Preferably, the emptying is centered on the axis of the cutting plate.
Ventajosamente, el vaciamiento presenta un fondo de perfil convexo.Advantageously, the emptying has a convex profile bottom.
De esta manera, durante la perforacion, el fondo del vaciamiento gufa las virutas de materia hacia el exterior del vaciamiento. El riesgo de acumulacion de virutas de materia y de atasco en el extremo del alma se limita.In this way, during drilling, the bottom of the emptying guides the chips of matter outwardly of the emptying. The risk of accumulation of matter chips and jam at the end of the soul is limited.
Siguiendo una forma de ejecucion, la porcion central de la tercera rama es mas ancha que la porcion distal de la tercera rama, de modo que la arista de corte de la tercera rama presenta un desnivel.Following a form of execution, the central portion of the third branch is wider than the distal portion of the third branch, so that the cutting edge of the third branch is uneven.
La porcion central de la tercera rama mas ancha que la porcion distal refuerza la tercera rama e impide su rotura. La tercera rama puede soportar mas presion que la primera rama y la segunda rama.The central portion of the third branch wider than the distal portion reinforces the third branch and prevents its breakage. The third branch can withstand more pressure than the first branch and the second branch.
Ventajosamente, la arista de corte de la tercera rama esta, al menos en parte, axialmente mas hacia adelante que la arista de corte de la primera rama y/o que la arista de corte de la segunda rama.Advantageously, the cutting edge of the third branch is, at least in part, axially further forward than the cutting edge of the first branch and / or than the cutting edge of the second branch.
De esta manera, la tercera rama esta dispuesta para soportar mas presion que la primera rama y/o la segunda rama.In this way, the third branch is arranged to withstand more pressure than the first branch and / or the second branch.
Preferentemente, la arista de corte de la tercera rama presenta una longitud inferior a la arista de corte de la primera rama y/o de la segunda rama.Preferably, the cutting edge of the third branch has a length less than the cutting edge of the first branch and / or the second branch.
De esta manera, la tercera rama soporta todavfa mas presion que la primera rama y la segunda rama. La penetracion de la plaqueta de corte se facilita y la cantidad de materia recortada en cada rotacion se incrementa. Por lo tanto, la velocidad de perforacion se mejora.In this way, the third branch withstands even more pressure than the first branch and the second branch. The penetration of the cutting plate is facilitated and the amount of material trimmed in each rotation is increased. Therefore, the drilling speed is improved.
La invencion se refiere igualmente a una herramienta de perforacion, tal como un taladro, caracterizada por que incluye:The invention also relates to a drilling tool, such as a drill, characterized in that it includes:
- un cuerpo de herramienta; y- a tool body; Y
- una plaqueta de corte tal como se ha presentado anteriormente, fijada a un extremo del cuerpo de herramienta.- a cutting plate as presented above, fixed to one end of the tool body.
